Tracking Clean Energy Progress

Assessing critical energy technologies for global clean energy transitions


The IEA’s Net Zero Emissions by 2050 Scenario (NZE) is a pathway for the global energy sector to achieve net zero CO2 emissions by 2050, while also achieving universal energy access by 2030 and major improvements in air quality.

But based on announced ambitions and pledges – as shown in the IEA's Announced Pledges Scenario (APS) – we are far from on track.

The IEA's Tracking Clean Energy Progress (TCEP) reports assess the status of 46 critical energy technologies and sectors and provides recommendations on how they can get 'on track' with the NZE.

What's on track?

Tracking Power

Not on track

Decarbonising the power sector is a fundamental step to reduce emissions, especially in an increasingly electrified world.

Tracking Fuel Supply

Not on track

A rapid step-change in policy and industry action is needed to cut flaring and methane emissions in the oil and gas sector.

Tracking Industry

Not on track

Industry processes that can't be easily electrified must cut emissions through efficiency, aggressive innovation and carbon capture.

Tracking Transport

Not on track

The transport sector will need to undergo a major transformation, including vastly improving efficiency and shifts from oil to electricity and other low-carbon fuels.

Tracking Buildings

Not on track

Unprecedented efficiency improvements are required in buildings, addressing growing demand from cooling, heating and powered devices.

Tracking Energy Integration

More efforts needed

Energy integration technologies will become increasingly important, especially as shares of variable renewables rise.
